Who was the smartest person in the history of our species? Solomon, Albert Einstein, Jesus, Nikola Tesla, Isaac Newton, Leonardo de Vinci, Stephen Hawking—who would you name.  We’ve had several individuals who broke the curve relative to intelligence.   As defined by the Oxford Dictionary of the English Language, IQ:

“an intelligence test score that is obtained by dividing mental age, which reflects the age-graded level of performance as derived from population norms, by chronological age and multiplying by100: a score of100 thus indicates performance at exactly the normal level for that age group. Abbreviation: IQ”

An intelligence quotient or IQ is a score derived from one of several different intelligence measures.  Standardized tests are designed to measure intelligence.  The term “IQ” is a translation of the German Intellizenz Quotient and was coined by the German psychologist William Stern in 1912.  This was a method proposed by Dr. Stern to score early modern children’s intelligence tests such as those developed by Alfred Binet and Theodore Simin in the early twentieth century.  Although the term “IQ” is still in use, the scoring of modern IQ tests such as the Wechsler Adult Intelligence Scale is not based on a projection of the subject’s measured rank on the Gaussian Bell curve with a center value of one hundred (100) and a standard deviation of fifteen (15).  The Stanford-Binet IQ test has a standard deviation of sixteen (16).  As you can see from the graphic below, seventy percent (70%) of the human population has an IQ between eighty-five and one hundred and fifteen.  From one hundred and fifteen to one hundred and thirty you are considered to be highly intelligent.  Above one hundred and thirty you are exceptionally gifted.

What are several qualities of highly intelligent people?  Let’s look.


  • A great deal of self-control.
  • Very curious
  • They are avid readers
  • They are intuitive
  • They love learning
  • They are adaptable
  • They are risk-takers
  • They are NOT over-confident
  • They are open-minded
  • They are somewhat introverted

You probably know individuals who fit this profile.  We are going to look at one right now:  John von Neumann.


The Financial Times of London celebrated John von Neumann as “The Man of the Century” on Dec. 24, 1999. The headline hailed him as the “architect of the computer age,” not only the “most striking” person of the 20th century, but its “pattern-card”—the pattern from which modern man, like the newest fashion collection, is cut.

The Financial Times and others characterize von Neumann’s importance for the development of modern thinking by what are termed his three great accomplishments, namely:

(1) Von Neumann is the inventor of the computer. All computers in use today have the “architecture” von Neumann developed, which makes it possible to store the program, together with data, in working memory.

(2) By comparing human intelligence to computers, von Neumann laid the foundation for “Artificial Intelligence,” which is taken to be one of the most important areas of research today.

(3) Von Neumann used his “game theory,” to develop a dominant tool for economic analysis, which gained recognition in 1994 when the Nobel Prize for economic sciences was awarded to John C. Harsanyi, John F. Nash, and Richard Selten.

John von Neumann, original name János Neumann, (born December 28, 1903, Budapest, Hungary—died February 8, 1957, Washington, D.C. Hungarian-born American mathematician. As an adult, he appended von to his surname; the hereditary title had been granted his father in 1913. Von Neumann grew from child prodigy to one of the world’s foremost mathematicians by his mid-twenties. Important work in set theory inaugurated a career that touched nearly every major branch of mathematics. Von Neumann’s gift for applied mathematics took his work in directions that influenced quantum theory theory of automation, economics, and defense planning. Von Neumann pioneered game theory, and, along with Alan Turing and Claude Shannon was one of the conceptual inventors of the stored-program digital computer .

Von Neumann did exhibit signs of genius in early childhood: he could joke in Classical Greek and, for a family stunt, he could quickly memorize a page from a telephone book and recite its numbers and addresses. Von Neumann learned languages and math from tutors and attended Budapest’s most prestigious secondary school, the Lutheran Gymnasium . The Neumann family fled Bela Kun’s short-lived communist regime in 1919 for a brief and relatively comfortable exile split between Vienna and the Adriatic resort of Abbazia. Upon completion of von Neumann’s secondary schooling in 1921, his father discouraged him from pursuing a career in mathematics, fearing that there was not enough money in the field. As a compromise, von Neumann simultaneously studied chemistry and mathematics. He earned a degree in chemical engineering from the Swiss Federal Institute in  Zurich and a doctorate in mathematics (1926) from the University of Budapest.

OK, that all well and good but do we know the IQ of Dr. John von Neumann?

John Von Neumann IQ is 190, which is considered as a super genius and in top 0.1% of the population in the world.

With his marvelous IQ, he wrote one hundred and fifty (150) published papers in his life; sixty (60) in pure mathematics, twenty (20) in physics, and sixty (60) in applied mathematics. His last work, an unfinished manuscript written while in the hospital and later published in book form as The Computer and the Brain, gives an indication of the direction of his interests at the time of his death. It discusses how the brain can be viewed as a computing machine. The book is speculative in nature, but discusses several important differences between brains and computers of his day (such as processing speed and parallelism), as well as suggesting directions for future research. Memory is one of the central themes in his book.

I told you he was smart!

On Thursday, Rep. Alexandria Ocasio-Cortez (D-N.Y.) and Sen. Ed Markey (D-Mass.) unveiled a landmark resolution cementing the pillars of an unprecedented program to zero out planet-warming emissions and restore the middle-class prosperity of postwar America that the original New Deal helped spur.

Just three months after calls for a Green New Deal electrified a long-stagnant debate on climate policy, the Democratic lawmakers released the six-page document outlining plans to cut global emissions forty (40) to sixty (60) percent below 2010 levels by 2030 and neutralize human-caused greenhouse gases entirely by 2050.

The joint resolution stakes out a “ten-year national mobilization” plan to build “smart” grids and rapidly increase the share of American power generated from solar and wind from ten (10) percent today to as close to one hundred (100) percent as possible over the next decade. The plan reframes tired talk of repairing the nation’s crumbling bridges, highways and ports as a crisis in a new era of billion-dollar storms. It gets local, demanding upgrades to “all existing U.S. buildings” to “achieve maximum” efficiency with energy and water use.

These are tremendously ambitious goals and quite frankly somewhat misguided.  The time line is NOT realistic.  We are, at the present time, not anywhere close to achieving those goals.  No programs in action to achieve those goals and one thing the “gentle” congresswoman misunderstands—the American love for fast cars, slow cars, electric cars, hybrid cars, etc. You surely must get my drift. Our entire economy has been built on fossil fuels.  That will continue using carbonaceous fuels until viable and cost-efficient alternatives are realized and commercially available.

The automotive industry thinks that time is down the road and they are operating with that belief. Let’s take a very quick look at what the automotive industry thinks is in store for our future “rides”.  The digital pictures below will give you some idea as to the concepts the industry is working on for future sales.

The E-Legend is an all-electric modern reinterpretation Peugeot’s 1969 -504 coupe. The automotive industry is making across-the-board moves to electric vehicles, and French manufacturer Peugeot isn’t about to be left behind. Ahead of the 2018 Paris Motor Show, Peugeot has released its E-Legend concept EV with a design that harks back to the classic 504 coupes of the 60s and 70s. In a world where aerodynamics leaves automotive design with a feeling of sameness across the industry, the E-Legend breaks from convention with a classically proportioned exterior and sharp features. The interior is nearly a modern masterpiece, with seats that could be at home in a modern office and a rectangular steering wheel. Peugeot claims 456 horsepower and 590 lb-ft of torque from the electric powertrain and a range of 373 miles, putting it right in line with current EV offerings. With its good looks and solid specs, the E-Legend is begging to see production.

Mercedes has unveiled the Vision EQ Silver Arrows Concept, and it is a stunner. The concept is a feast for the senses, a product of Mercedes’ masterful use of its own heritage and reinventing it with a futuristic electric-jolted twist. As it is, the EQ Silver Arrow is a showcase concept — and what a concept, it is — that we’ll never see in production form. The good news is that the concept isn’t just a muscle-flexing design exercise, too. Parts of the concept will appear in Mercedes’ new electric brand offshoot, EQ. As to what those parts are? We’ll just have to wait and find out.

Porsche has announced that it will put the Cross Turismo into production as a variant of the upcoming Taycan EV, creating 300 new jobs at Porsche’s Zuffenhausen headquarters. The reports of the wagon’s death have been greatly exaggerated, and the Porsche Mission E Cross Turismo concept is the latest proof that the body style is alive and well. Following the path blazed by the raised ride height and plastic-clad wheel arches of its corporate cousin, the Audi A4 All-road, the Mission E Cross Turismo is an all-electric, off-road-ready wagon that’s nonetheless claimed to be capable of blasting to 60 mph in less than 3.5 seconds and to 124 mph in less than 12 seconds.That’s right, Porsche is hinting that boxer engines won’t be the only characteristic its vehicles share with Subarus, and the Mission E Cross Turismo reveals the brand is, at the very least, considering an Outback-like variant of its upcoming Mission E sedan. Presumably, such a model will accompany a lower-riding, cladding-free, and non-knobby-tired Sport Turismo wagon version of the Mission E, as well.

“In our striving for efficiency, have we lost empathy for the traveler?” These words, from Volvo’s launch video for its new 360c fully autonomous concept car, hit home with me. I fly a lot, so I’m fully familiar with efficient but unsympathetic forms of travel, and Volvo’s idea is to help people like me through the design of its future cars. The Volvo 360c is, like most concepts of our time, all-electric, fully autonomous, and covered by a big sweeping glass dome. What distinguishes it, though, is Volvo’s vision of how it fits into the broader scheme of city infrastructure, short-haul flights, working commutes, and environmental concerns.

The PB18 e-tron concept embodies a fundamentally driver-centric sports car — there are no piloted driving systems to add weight, and its relatively lightweight construction helps propel it to speeds above 186 mph. It features a large-format cockpit which is a freely programmable unit and can be switched between layouts for optimal racetrack- and road-driving. The driver’s seat and cockpit are integrated into an inner monocoque shell that can be slid laterally to accommodate for one- or two-person seating.

The all-electric I.D. Vizzion will have a production version with a steering wheel and Level 4 autonomy on board, but the concept being shown off on the Geneva floor was the one with full autonomy and no human controls. To look at the expansive opening created by the Vizzion’s vast doors and the carpeted interior and contoured seating inside, you’d be reminded of Aston Martin’s similarly grand Lagonda concept car. But where the Aston Martin is sumptuous and enticing, VW’s carpet is made out of an unpleasant synthetic material, and the entire interior feels cheaper than it looks.

There’s not much in the way of features on the inside of the I.D. Vizzion: like most concepts, it’s minimal and stripped down, with only a shelf at the front of the car for tossing your sunglasses onto. There are wireless charging pods for phones, which are increasingly becoming a standard feature even in current production models.


As you can see, the automobile industry is planning on a long and continued future although all-electric and autonomous vehicles are definitely in the future.  Please let me have your comments. See if you and I agree at all.

I always marvel at the pace of technology and how that technology fills a definite need for products only dreamt of previously.   We all have heard that “necessity is the mother of invention” well, I believe that to a tee.  We need it, we can’t find it, no one makes it, let’s invent it.  This is the way adults solve problems.  Every week technology improves our lives giving us labor-saving devices that “tomorrow” will become commonplace.  All electro-mechanical devices run on amperage provided by voltage impressed.   Many of these devices use battery power for portability.   Lithium-ion batteries seem to be the batteries of choice right now due to their ability to hold a charge and their ability to fast-charge.

Pioneer work with the lithium battery began in 1912 under G.N. Lewis but it was not until the early 1970s when the first non-rechargeable lithium batteries became commercially available. lithium is the lightest of all metals, has the greatest electrochemical potential and provides the largest energy density for weight.

The energy density of lithium-ion is typically twice that of the standard nickel-cadmium. This is a huge advantage recognized by engineers and scientists the world over.  There is potential for higher energy densities. The load characteristics are reasonably good and behave similarly to nickel-cadmium in terms of discharge. The high cell voltage of 3.6 volts allows battery pack designs with only one cell. Most of today’s mobile phones run on a single cell. A nickel-based pack would require three 1.2-volt cells connected in series.

Lithium-ion is a low maintenance battery, an advantage that most other chemistries cannot claim. There is no memory and no scheduled cycling is required to prolong the battery’s life. In addition, the self-discharge is less than half compared to nickel-cadmium, making lithium-ion well suited for modern fuel gauge applications. lithium-ion cells cause little harm when disposed.

If we look at advantages and disadvantages, we see the following:


  • High energy density – potential for yet higher capacities.
  • Does not need prolonged priming when new. One regular charge is all that’s needed.
  • Relatively low self-discharge – self-discharge is less than half that of nickel-based batteries.
  • Low Maintenance – no periodic discharge is needed; there is no memory.
  • Specialty cells can provide very high current to applications such as power tools.


  • Requires protection circuit to maintain voltage and current within safe limits.
  • Subject to aging, even if not in use – storage in a cool place at 40% charge reduces the aging effect.
  • Transportation restrictions – shipment of larger quantities may be subject to regulatory control. This restriction does not apply to personal carry-on batteries.
  • Expensive to manufacture – about 40 percent higher in cost than nickel-cadmium.
  • Not fully mature – metals and chemicals are changing on a continuing basis.

One amazing property of Li-Ion batteries is their ability to be formed.  Let’s take a look.

Researchers have just published documentation relative to a new technology that will definitely fill a need.


Researchers at the Ulsan National Institute of Science and Technology in Korea have developed an imprintable and bendable lithium-ion battery they claim is the world’s first, and could hasten the introduction of flexible smart phones that leverage flexible display technology, such as Samsung’s Youm flexible OLED.

Samsung first demonstrated this display technology at CES 2013 as the next step in the evolution of mobile-device displays. The battery could also potentially be used in other flexible devices that debuted at the show, such as a wristwatch and a tablet.

Ulsan researchers had help on the technology from Professor John A. Rogers of the University of Illinois, researchers Young-Gi Lee and Gwangman Kim of Korea’s Electronics and Telecommunications Research Institute, and researcher Eunhae Gil of Kangwon National University. Rogers was also part of the team that developed a breakthrough in transient electronics, or electronics that dissolve inside the body.

The Korea JoongAng Daily newspaper first reported the story, citing the South Korea Ministry of Education, Science and Technology, which co-funded the research with the National Research Foundation of Korea.

The key to the flexible battery technology lies in nanomaterials that can be applied to any surface to create fluid-like polymer electrolytes that are solid, not liquid, according to Ulsan researchers. This is in contrast to typical device lithium-ion batteries, which use liquefied electrolytes that are put in square-shaped cases. Researchers say this also makes the flexible battery more stable and less prone to overheating.

“Conventional lithium-ion batteries that use liquefied electrolytes had problems with safety as the film that separates the electrolytes may melt under heat, in which case the positive and negative may come in contact, causing an explosion,” Lee told the Korean newspaper. “Because the new battery uses flexible but solid materials, and not liquids, it can be expected to show a much higher level of stability than conventional rechargeable batteries.”

This potential explosiveness of the materials in lithium-ion batteries — which in the past received attention because of exploding mobile devices — has been in the news again recently in the case of the Boeing 787 Dreamliner, which has had several instances of liquid leaking lithium-ion batteries. The problems have grounded Boeing’s next-generation jumbo jet until they are investigated and resolved.

This is a very short posting but one I felt would be of great interest to my readers.  New technology; i.e. cutting-edge stuff, etc. is fun to write about and possibly useful to learn.  Hope you enjoy this one.

More and more engineers, systems analysist, biochemists, city planners, medical practitioners, individuals in entertainment fields are moving towards computer simulation.  Let’s take a quick look at simulation then we will discover several examples of how very powerful this technology can be.


Simulation modelling is an excellent tool for analyzing and optimizing dynamic processes. Specifically, when mathematical optimization of complex systems becomes infeasible, and when conducting experiments within real systems is too expensive, time consuming, or dangerous, simulation becomes a powerful tool. The aim of simulation is to support objective decision making by means of dynamic analysis, to enable managers to safely plan their operations, and to save costs.

A computer simulation or a computer model is a computer program that attempts to simulate an abstract model of a particular system. … Computer simulations build on and are useful adjuncts to purely mathematical models in science, technology and entertainment.

Computer simulations have become a useful part of mathematical modelling of many natural systems in physics, chemistry and biology, human systems in economics, psychology, and social science and in the process of engineering new technology, to gain insight into the operation of those systems. They are also widely used in the entertainment fields.

Traditionally, the formal modeling of systems has been possible using mathematical models, which attempts to find analytical solutions to problems enabling the prediction of behavior of the system from a set of parameters and initial conditions.  The word prediction is a very important word in the overall process. One very critical part of the predictive process is designating the parameters properly.  Not only the upper and lower specifications but parameters that define intermediate processes.

The reliability and the trust people put in computer simulations depends on the validity of the simulation model.  The degree of trust is directly related to the software itself and the reputation of the company producing the software. There will considerably more in this course regarding vendors providing software to companies wishing to simulate processes and solve complex problems.

Computer simulations find use in the study of dynamic behavior in an environment that may be difficult or dangerous to implement in real life. Say, a nuclear blast may be represented with a mathematical model that takes into consideration various elements such as velocity, heat and radioactive emissions. Additionally, one may implement changes to the equation by changing certain other variables, like the amount of fissionable material used in the blast.  Another application involves predictive efforts relative to weather systems.  Mathematics involving these determinations are significantly complex and usually involve a branch of math called “chaos theory”.

Simulations largely help in determining behaviors when individual components of a system are altered. Simulations can also be used in engineering to determine potential effects, such as that of river systems for the construction of dams.  Some companies call these behaviors “what-if” scenarios because they allow the engineer or scientist to apply differing parameters to discern cause-effect interaction.

One great advantage a computer simulation has over a mathematical model is allowing a visual representation of events and time line. You can actually see the action and chain of events with simulation and investigate the parameters for acceptance.  You can examine the limits of acceptability using simulation.   All components and assemblies have upper and lower specification limits a and must perform within those limits.

Computer simulation is the discipline of designing a model of an actual or theoretical physical system, executing the model on a digital computer, and analyzing the execution output. Simulation embodies the principle of “learning by doing” — to learn about the system we must first build a model of some sort and then operate the model. The use of simulation is an activity that is as natural as a child who role plays. Children understand the world around them by simulating (with toys and figurines) most of their interactions with other people, animals and objects. As adults, we lose some of this childlike behavior but recapture it later on through computer simulation. To understand reality and all of its complexity, we must build artificial objects and dynamically act out roles with them. Computer simulation is the electronic equivalent of this type of role playing and it serves to drive synthetic environments and virtual worlds. Within the overall task of simulation, there are three primary sub-fields: model design, model execution and model analysis.


The following examples are taken from computer screen representing real-world situations and/or problems that need solutions.  As mentioned earlier, “what-ifs” may be realized by animating the computer model providing cause-effect and responses to desired inputs. Let’s take a look.

A great host of mechanical and structural problems may be solved by using computer simulation. The example above shows how the diameter of two matching holes may be affected by applying heat to the bracket


The Newtonian and non-Newtonian flow of fluids, i.e. liquids and gases, has always been a subject of concern within piping systems.  Flow related to pressure and temperature may be approximated by simulation.


The Newtonian and non-Newtonian flow of fluids, i.e. liquids and gases, has always been a subject of concern within piping systems.  Flow related to pressure and temperature may be approximated by simulation.

Electromagnetics is an extremely complex field. The digital above strives to show how a magnetic field reacts to applied voltage.

Chemical engineers are very concerned with reaction time when chemicals are mixed.  One example might be the ignition time when an oxidizer comes in contact with fuel.

Acoustics or how sound propagates through a physical device or structure.

The transfer of heat from a colder surface to a warmer surface has always come into question. Simulation programs are extremely valuable in visualizing this transfer.


Equation-based modeling can be simulated showing how a structure, in this case a metal plate, can be affected when forces are applied.

In addition to computer simulation, we have AR or augmented reality and VR virtual reality.  Those subjects are fascinating but will require another post for another day.  Hope you enjoy this one.

How many “screen-time” hours do you spend each day?  Any idea? Now, let’s face facts, an adult working a full-time job requiring daily hour-long screen time may be a necessity.  We all know that but how about our children and grandchildren?

I’m old enough to remember when television was a laboratory novelty and telephones were “ringer-types” affixed to the cleanest wall in the house.  No laptops, no desktops, no cell phones, no Gameboys, etc etc.  You get the picture.  That, as we all know, is a far cry from where we are today.

Today’s children have grown up with a vast array of electronic devices at their fingertips. They can’t imagine a world without smartphones, tablets, and the internet.  If you do not believe this just ask them. One of my younger grandkids asked me what we did before the internet.  ANSWER: we played outside, did our chores, called our friends and family members.

The advances in technology mean today’s parents are the first generation who have to figure out how to limit screen-time for children.  This is a growing requirement for reasons we will discuss later.  While digital devices can provide endless hours of entertainment and they can offer educational content, unlimited screen time can be harmful. The American Academy of Pediatrics recommends parents place a reasonable limit on entertainment media. Despite those recommendations, children between the ages of eight (8) and eighteen (18) average seven and one-half (7 ½) hours of entertainment media per day, according to a 2010 study by the Henry J. Kaiser Family Foundation.  Can you imagine over seven (7) hours per day?  When I read this it just blew my mind.

But it’s not just kids who are getting too much screen time. Many parents struggle to impose healthy limits on themselves too. The average adult spends over eleven (11) hours per day behind a screen, according to the Kaiser Family Foundation.  I’m very sure that most of this is job related but most people do not work eleven hours behind their desk each day.

Let’s now look at what the experts say:

  • Childrenunder age two (2) spend about forty-two (42) minutes, children ages two (2) to four (4) spend two (2) hours and forty (40) minutes, and kids ages five (5) to eight (8) spend nearly three (3) hours (2:58) with screen media daily. About thirty-five (35) percent of children’s screen time is spent with a mobile device, compared to four (4) percent in 2011. Oct 19, 2017
  • Children aged eighteen (18) monthsto two (2) years can watch or use high-quality programs or apps if adults watch or play with them to help them understand what they’re seeing. children aged two to five (2-5) years should have no more than one hour a day of screen time with adults watching or playing with them.
  • The American Academy of Pediatrics released new guidelines on how much screen timeis appropriate for children. … Excessive screen time can also lead to “Computer Vision Syndrome” which is a combination of headaches, eye strain, fatigue, blurry vision for distance, and excessive dry eyes. August 21, 2017
  • Pediatricians: No More than two (2) HoursScreen Time Daily for Kids. Children should be limited to less than two hours of entertainment-based screen time per day, and shouldn’t have TVs or Internet access in their bedrooms, according to new guidelines from pediatricians. October 28, 2013

OK, why?

  • Obesity: Too much time engaging in sedentary activity, such as watching TV and playing video games, can be a risk factor for becoming overweight.
  • Sleep Problems:  Although many parents use TV to wind down before bed, screen time before bed can backfire. The light emitted from screens interferes with the sleep cycle in the brain and can lead to insomnia.
  • Behavioral Problems: Elementary school-age children who watch TV or use a computer more than two hours per day are more likely to have emotional, social, and attention problems. Excessive TV viewing has even been linked to increased bullying behavior.
  • Educational problems: Elementary school-age children who have televisions in their bedrooms do worse on academic testing.  This is an established fact—established.  At this time in our history we need educated adults that can get the job done.  We do not need dummies.
  • Violence: Exposure to violent TV shows, movies, music, and video games can cause children to become desensitized to it. Eventually, they may use violence to solve problems and may imitate what they see on TV, according to the American Academy of Child and Adolescent Psychiatry.

When very small children get hooked on tablets and smartphones, says Dr. Aric Sigman, an associate fellow of the British Psychological Society and a Fellow of Britain’s Royal Society of Medicine, they can unintentionally cause permanent damage to their still-developing brains. Too much screen time too soon, he says, “is the very thing impeding the development of the abilities that parents are so eager to foster through the tablets. The ability to focus, to concentrate, to lend attention, to sense other people’s attitudes and communicate with them, to build a large vocabulary—all those abilities are harmed.”

Between birth and age three, for example, our brains develop quickly and are particularly sensitive to the environment around us. In medical circles, this is called the critical period, because the changes that happen in the brain during these first tender years become the permanent foundation upon which all later brain function is built. In order for the brain’s neural networks to develop normally during the critical period, a child needs specific stimuli from the outside environment. These are rules that have evolved over centuries of human evolution, but—not surprisingly—these essential stimuli are not found on today’s tablet screens. When a young child spends too much time in front of a screen and not enough getting required stimuli from the real world, her development becomes stunted.

CONCLUSION: This digital age is wonderful if used properly and recognized as having hazards that may create lasting negative effects.  Use wisely.

Jumper begins with Davey, a child who has spent the entirety of his life being verbally and physically abused by his alcoholic father. When reading the book, I immediately took a very sympathetic stance relative to Davey’s situation. I cannot imagine growing up on a household with this atmosphere.  He and his mother were routinely pummeled by the “man of the house” and the brutality at times was graphic.   When I say graphic, I mean Davey’s mother had to have reconstructive surgery after her last beating.  This is when she left.  When she did leave, unable to deal with the abuse she suffered, it only got worse for him. He was abandoned by the only person in the world who ever cared for him.   He was left with the man who frequently beat him bloody, Davey finally finds escape when he discovers his ability to Jump, or teleport, to any place that he has previously been, and can remember well enough to picture in his mind. He discovers this ability quite by accident.  His mother lies comatose on the kitchen floor, having been beaten by her husband and Davey is lying on the floor with his father on top of him throwing punches.  He visualizes the only safe place he knows—the local public library.  That’s when he first jumps.  He has no idea as to how he did this.  After the beating, he runs away and tries to make a new life for himself. It is definitely not easy for a seventeen-year-old out on his own, with no money, no drivers’ license, no passport, no Social Security number and no birth certificate.  No identification at all. Out of desperation, he finally decides the only way he can survive is to rob a bank using his powers. This happens in the movie as well but is one of the few similarities between the two—very few.  However, where Davey’s desperate circumstances and real need are deeply delved into in the book.   He is forced to steal the money just to survive, promising to himself one day to pay it back, something he actually, eventually does.  With the money he is able to improve his living standards and actually begin to enjoy his young life not having to worry about the abuse.

He meets a girl named Millie, falls in love, and over the course of the novel finds someone who is willing to listen to his story.  This includes all of the horrible, terrible things that he has had to live through, and has kept pent up inside himself his entire life. She urges him to seek out his mother, and he does just that but the result is a terrible event that determines, to some extent, his future.

In my opinion, the book is much much better than the movie.  The characters are vivid and compelling with Davy and Millie trying to determine the method by which Davy is able to teleport. (NOTE: Teleportation is the theoretical transfer of matter or energy from one point to another without traversing the physical space between them.) The book does NOT come to any conclusions but they do establish the fact that there is a portal through which Davy leaps when he jumps.

What Others Think:

I think this is a terrific book but I would like you to read the book and judge for yourself. I also would like to give you what others think.

Mar 17, 2014  Gavin rated it really liked it

I’ve wanted to read this ever since I watched the Jumper movie. Teleportation movies and books are always fun. The biggest surprise is that this book was nothing like the movie. The only thing they had in common was the teleporting main character.

This was a surprisingly dark sci-fi that spent more time pondering moral dilemmas and exploring Davey’s emotional reaction to the various mishaps that befell him than it did on action sequences. The action and the pace did pick up a bit towards the end.

Davey was a tortured soul with a bit of bitterness about him, but for all his faults he was mostly likable.

Overall this was an enjoyable sci-fi read worth a 4-star rating. I’ll definitely read the rest of the books in the series at some point.

Nov 21, 2013  Eric Allen rated it it was amazing

By Steven Gould

A Retroview by Eric Allen

When this book came out, back in 1992, I was in my teens, had just finished the latest installment of The Wheel of Time, and I was looking for something else to read. So, I did the thing that all geeks do, and asked the librarian for a recommendation. She handed me Jumper with a wink and told me that I had better hurry because the book was about to be banned at that library. Being a teenaged boy at the time, these were the exact words needed to sell me on it. And I must say, I was really blown away by it. It was a book written for someone my age, that wasn’t afraid to treat me like an adult, showing such things as homosexual child rape, child abuse, alcoholism, graphic terrorist attacks, and it even used the dreaded F word like FOUR WHOLE TIMES!!! No wonder that behind Catcher in the Rye, it is the most banned children’s book in history. A fact that the author is extraordinarily proud of.

Davy Rice has a special gift: the ability to transport himself to any spot he wants, which he discovers when being beaten by his abusive father or about to be raped by a long-haul trucker. He flees his small town, moving to NY, where he settles down after jumping into a bank and taking almost $1 million. He falls in love with a college student in Oklahoma, and eventually decides to find his mother, who deserted him. But disaster strikes and Davy begins to use his gift to find the culprit, drawing the unwanted attention of the NSA and NY Police Department. Improbable, of course, but Davy is a moral, sensitive protagonist, dealing with complex issues.

Sherwood Smith rated it it was amazing

I call it science fiction though the jumping is probably fantasy, but the book is treated like SF. The original book, not the novelisation for the movie, was heart-wrenching, funny, fast-paced, poignant, and so very real in all the good ways, as the teen protagonist discovers he can teleport from place to place, at first to escape his abusive dad. Then he wants to do good . . . and discovers that there are consequences–from both sides.

I’m sorry that the movie appears to have removed all the heart from it, leaving just the violence, without much motivation, judging from the novelization that appeared afterward. No doubt many readers liked it, but that was not my cup of tea.


As I mentioned above, read the book and determine for yourself if it’s a winner.  Easy to read, three hundred and forty-five (345) pages double-spaced.  Good night’s work.

One of the things I like to do with my posts is deliver information you can use in your daily life. “Stuff” that just mike make a difference.  I certainly hope this one does.    Some of the information you will read is taken from Consumer Reports Magazine and Design News Daily Magazine.

Consumer Reports recently published information regarding the reliability of automobiles offered for sale in the United States.  They drew their conclusions from owner surveys of more than five hundred thousand (500,000) people. The surveys look at numerous problem areas including engine, transmission, suspension, cooling, electrical, climate, brakes, exhaust, paint, trim, noises, leaks, power equipment, and in-car electronics, among others.  We will highlight now those automobiles considered to be the most unreliable.  This list may surprise you as it did me.

I would say that if you are looking for new wheels you heed the information given by Consumer Magazine.  They accept no advertisements and generally conduct their research by interviewing consumers and actually testing the products they report on.
